Hi, I am suffering from a problem.
I want get the results when I run "ineqdeco" command, but I can't.

For example, when I run the code below,
Code:
sysuse auto
ineqdeco mpg

return list
the result is
Code:
scalars:
                  r(N) =  0.
(Of course, there is no problem in "ineqdeco mpg" command. I just omitted the calculation results for simplisity)

In this case, how can I get the results?
Thank you for your time spending to read this question.
